The chestnut-rumped heathwren (Hylacola pyrrhopygia) is a species of bird in the family Acanthizidae. It is endemic to temperate and subtropical forests and heathlands of Australia.

Both sexes have a dull white eyebrow; eyes are yellow, while... Wikipedia →

Rare
Under 5% of wildlife watchers report a Calamanthus pyrrhopygius sighting in Grampians National Park on a given day, based on 26 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 106th most-seen of the 145 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May and July
In those months about 10% of wildlife watchers report a Calamanthus pyrrhopygius in Grampians National Park on a given day, against under 5% in June and August–April, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Calamanthus pyrrhopygius sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 4
Of the 4 parks where we can rate Calamanthus pyrrhopygius sightings, Grampians National Park ranks 3rd at under 5%. The best odds are in Great Otway National Park (Australia, about 10%) and Royal National Park (Australia, about 10%).
Same family: Acanthizidae
The closest relatives of the Calamanthus pyrrhopygius that you can see in Grampians National Park (family Acanthizidae, Thornbills and Allies) are White-browed Scrubwren (about 60%), Brown Thornbill (about 60%) and Striated Thornbill (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Calamanthus pyrrhopygius is recorded against all the birds logged in Grampians National Park (26 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
